Abstract :
The negative sequence current monitoring instrument named NSCM can monitor the negative sequence current, which affect the safety and stability of the generator directly according to the criterion when generator drive unbalanced load The hardware structure of the NSCM and the algorithm of the negative sequence based on average filtering are expressed in this paper. Multi-task operation and Ethernet communicating based on μC/OS-II can improve the work in the scene.
